Password checker code

Here is an example of what I can do with PHP! I created a password checker that makes sure a password is a strong password!

<script language=”php”>

//load selected passwords for checking
$passwords=array(
“NoDigitsOrOthers”,
“NoDigits…”,
“NoOthers999″,
“2 Spaces !”,
“0LOWERCASE?”,
“0uppercase+”,
“Sh0r+”,
“This1IsMuchTooLongForAPassword!”,
“1GoodPassword.”,
“GoodPassword2!”
);

// create a function to act as the password checker
Function password_checker($passwords)
{
// create a password strength meter
$isstrong=7;

//1the string should have atleast 8 char
if(preg_match(“/.{8}/”,$passwords)==0)
{
echo “$passwords is not a strong password:It does not contain the minimum amount of charactors”;
// password is getting “weaker”
$isstrong= –$isstrong;
}

//2the string must contain fewer than 16 chars
if(preg_match(“/.{17}/”,$passwords)==1)
{
echo “$passwords is not a strong password:It contains too many charactors”;
// password is getting “weaker”
$isstrong= –$isstrong;
}

//3string must have atleast 1 number
if(preg_match(“/[0-9]{1,}/”,$passwords)==0)
{
echo “$passwords is not a strong password:It does not contain enough numbers”;
// password is getting “weaker”
$isstrong= –$isstrong;
}

if(preg_match(“/[A-Z]{1,}/”,$passwords)==0)

if(preg_match(“/\s/”,$passwords)==1)
{
echo “$passwords is not a strong password: It cannot contain spaces”;
// password is getting “weaker”
$isstrong= –$isstrong;
}

if($isstrong==7)
{
echo “$passwords is a strong password”;
}
}

// check all passwords in list
// set array bound for iterating through an array of any length
$arraybound=count($passwords);
for ($passtrial = 0; $passtrial < $arraybound; $passtrial++)
{
password_checker($passwords[$passtrial]);

Paycheck calculator

Here is the form handler of a paycheck calculator I created as part a project on my PHP course. I found it useful calculating how much I would be making simply from my phone.

<h2 style=”text-align: center “> Process Paycheck Data</h2>

<?php

$totalcheck=0;
$overtimepay=0;
$overtimehr=0;
$totalhours=0;
$finalcheck=0;

// calculate paycheck
$HoursWorked= $_POST[‘hours’];
$HourlyWage= $_POST[‘wage’];
//cover overtime
if($HoursWorked>40)
{
$overtimehr=($HoursWorked-40);
$overtimewage=($HourlyWage*1.5);
$totalcheck= 40*$HourlyWage;
$overtimepay= $overtimehr*$overtimewage;
$totalhours=$overtimehr+40;
$finalcheck=$overtimepay+$totalcheck;

echo “40 hours @ $HourlyWage /hr = \$$totalcheck”;
echo “$overtimehr hours @ $overtimewage /hr = \$$overtimepay”;
echo “ Total for $totalhours hours is \$$finalcheck “;

}
else
{
if($error==0)
{
$totalcheck=$HoursWorked*$HourlyWage;
echo “ $HoursWorked @ $HourlyWage /hr = \$ $totalcheck”;
}

}

print( ‘<a href=”http://127.0.0.1/paycheck.html”>Caluclate Another Paycheck</a>’);
